Use the first eight rules of inference to derive the conclusion of the following symbolized argument: 1.  (C ⊃ N) • E2.  D v (N ⊃ D)3.  ~D                       / ~C v P

For the following lists of premises, derive the indicated conclusion and complete the justification.  1. G ⊃ (N ⊃ K)2. R v (D ⊃ F)3. S • (T v U)4.                            , Dist

 Identify the main operator in the following proposition: E • [(F ⊃ A) v (~G v H)]

Use the change of quantifier rule together with the eighteen rules of inference to derive the conclusions of the following symbolized argument: (Ǝx)(Ax v Bx) ⊃ (x)Cx (Ǝx)~Cx                          / ~(Ǝx)Ax

Forces of 56 N and 52 N are applied at the ends of a meter stick and a force of 65 N is applied at its center as shown. Determine the torque on the meter stick about the point P due to these forces. 2325 F3 torque.png

pendulum (1).png The simple pendulum is released, from rest, at point A.  What is its speed at point B?

p7 (1).png Two objects are connected by a rope over a massless, frictionless, pulley. The coefficient of static friction between the surface and m2 is μ = 0.600.  Determine the minimum mass for m2 to slide down the ramp for m1 = 12.0 kg and θ = 35.00

2325 F2 bullet.png A 250 g uniform meter stick is vertical and pivoted about its center. A 15.0 g bullet traveling horizontally at 250 m/s strikes the meter stick at the 75.0 cm mark and emerges traveling at 140 m/s. What is the angular speed of the meterstick after the bullet emerges? moment of inertia of meter stick = 1/12 mass x (length)2
